Description
Technical field
The present invention relates to a kind of vacuum cleaner low noise motor device, be particularly suited for carpet and floor-cleaning
The Noise measarement of household or industrial vacuum cleaner.
Background technology
It is known that vacuum motor is the core of vacuum cleaner, the performance of vacuum motor largely affects
The performance of vacuum cleaner.In the performance parameter of vacuum cleaner, noise is weigh vacuum cleaner one
Very important parameter index, is also to directly affect consumer most to use, the key factor of sense learning through practice.With
The release that the competition day by day in market and nearest European Union ERP (Energy related Products) instruct, right
Vacuum cleaner noise proposes and clearly requires, and must accomplish to the noise requirements of vacuum cleaner in 2017
Within 80dB (A), and require clearly to indicate phase noise figure to the vacuum cleaner on market.
In the design of dust catcher, generally also need to vacuum in addition to the Noise measarement of motor (noise source) itself
Dust catcher total noise of centrifuge is controlled.Main means are: 1, damping, i.e. reduce the vibration of vibroseis, actively drop
Make an uproar；2, vibration isolation, vibroseis will be primarily referred to as the vibrations of motor and isolate, stop the transmission of vibrations and put
Greatly；3, sound absorption, will noise absorbent, convert acoustic energy into heat energy, mainly use sound-absorbing material；4, sound insulation, i.e.
Use acoustic hood to isolate noise, stop noise transmission.The noise of motor of usual vacuum cleaner exists
In the range of 95-105dB (A), productive noise is made the reasonable level that can accomplish 92dB (A), more down
Drop just extremely difficult, it is necessary to take way above to carry out actively control to noise.
In the actual design of dust catcher is applied, the sound insulation of dust catcher generally uses the plastic construction of injection, has
Also using the sound insulation of double-layer plastic structure to make an uproar, the acoustic hood of plastics is thicker, and rigidity is more good more is beneficial to noise reduction, technology
Research shows that the surface density of acoustic hood is bigger, and sound insulation property is better；Sound absorption is mainly in the inside of acoustic hood or true
The materials such as deadener, the usual sound-absorbing sponge using loose structure, mineral wool are placed in the housing of vacuum cleaner,
Sound-absorbing material is more, and the punching rate of sound-absorbing material is higher, and acoustic absorptivity is higher, is more beneficial to noise reduction；Eliminate the noise generally
Use structure to eliminate the noise, such as do expansion air channel, increase the length etc. in dust catcher air inlet/outlet air channel；Vibration isolation is mainly led to
Cross the soft material such as damping materials such as rubber, stop the transmission of vibrations, prevent from shaking other that be transmitted to dust catcher
Parts, amplify vibrations；Damping generally uses the soft material that can receive vibroseis very well, wraps up vibroseis, will shake
Move and be converted to heat energy, be usually predominantly and place substantial amounts of polyurethane foam material in the fan housing position of vacuum cleaner
Material, carries out damping.Usual Horizontal Vacuum Cleaner, can be controlled by the application noise of above technology and arrive to 76
The level of 82dB (A), due to the restriction in space, and in vertical type dust collector, it is impossible to use double acoustic cover, and
Enough deadeners, generally can control the level to 82 to 88dB (A), more down just relatively difficult.
And people is receptible, does not produce dislike and the noise level detested be about 68 and arrive 80dB (A) level below,
So the noise level of current vacuum cleaner also falls far short from the requirement of people, especially in utilization rate not
It is the area that very high non-carpet uses, the so high noise water of a lot of families vacuum cleaner beyond affordability
Flat, even if in the reasonable horizontal dust collector of Noise measarement, owing to using substantial amounts of deadener and multilayer
Plastics acoustic enclosure structure, the volume causing vacuum cleaner is very huge, and cost is also very high, and market connects
Degree of receiving is low.
How to realize, while reducing noise, being substantially reduced the volume of acoustic hood and vacuum cleaner, reduce true
Vacuum cleaner air channel length, reduces the complexity in vacuum cleaner air channel, effectively reduces the use of deadener,
Especially in upright vacuum cleaner, under limited space, reduce the noise of vacuum cleaner, reduce true
The design and use cost of vacuum cleaner is the very important realistic problem that current the sector faces.
Content of the invention:
It is an object of the invention to provide a kind of vacuum cleaner low noise motor device, can solve
The problem of current vacuum cleaner noise, can be effectively reduced the external form volume of vacuum cleaner, improves dust catcher
The standardized rate of design, lowers the design and use cost of vacuum cleaner.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of vacuum cleaner low noise motor device, includes for providing the true of vacuum source for vacuum cleaner
Empty motor, carries out the acoustic hood of noise reduction to the work noise of described vacuum motor, it is characterised in that described every
Acoustic shell inwall forms a continuous cavity of connection, and described vacuum motor is positioned at described cavity, described cavity
Having unique opening, described vacuum motor has the motor air inlet that air-flow flows into, opening of described cavity
The direction of mouth is consistent with the direction of the motor air inlet of described vacuum motor.
Opening described further is annular, and described opening central axis and described motor air inlet
Central axis coincides mutually.
Acoustic hood described further could be arranged to the individual layer acoustic hood of only individual course structure or includes
Inner cover and the double acoustic cover of outer cover composition.
Also include shock absorbing ring and the setting of the motor fan housing one end being arranged at described vacuum motor further
In the beam of electric machine support one end of described vacuum motor, by described shock absorbing ring and described damping
Described vacuum motor is fixably attached in described cavity by pad.
Being provided with multiple air-out passages on yet further described shock absorbing ring, described vacuum motor produces
Air-flow flow into from described motor air inlet, pass sequentially through described motor fan housing, electric machine support, cavity,
With described air-out passage, then discharge from described opening.
It is provided with for reducing noise further between selectively described cavity and described vacuum motor
Porous sound absorbing materials.
It is 0.3 plastic material arriving 3mm or sheet metal material that yet further described acoustic hood uses thickness
Material makes.
The area of the opening of preferentially described annular is set to 1200 to 3500 square millimeters.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
The vacuum cleaner low noise motor device of this technology uses the acoustic hood of unique technology, according to noise control
The requirement of system is different, uses the individual layer acoustic hood of different-thickness and double-deck or double-layer vacuum acoustic enclosure structure；Simultaneously
From ordinary vacuum cleaner acoustic hood also unlike its described acoustic hood inwall formed continuous print cavity and
Described cavity has unique opening, the motor of the opening direction of described cavity and described vacuum motor
The direction of air inlet is consistent, and the air-flow of vacuum cleaner travels back across vacuum from described cavity after motor outflow
The motor fan housing direction of motor, the air-out passage arranging on described shock absorbing ring flows out, and so fully ensures
Cover acoustic control on each face for the vacuum cleaner, thus it is effectively reduced noise, reduce vacuum cleaner
Volume, reduces the design and use cost of product.
